To all whom it may concern:

Be it known that I, ROBERT L. HOLLIDAY, a citizen of the United States,residing at York avenue and The Terrace, New Bri hton, Staten Island,New York, have 1nvented certain new and useful Improvements inPaint-Screening Apparatus, fully described and represented in thefollowing specification and the accompanying drawings, forming a part ofthe same.

This invention relates to means for straining such substances as paint,which may be supplied continuously to the straining device durin itsoperation and the supply cut olli' when 1t is necessary to clean out thesediment from the straining device.

The straining device claimed herein is of cylindrical shape, andrequires a brush to be rotated or carried around within its cylindricalsurface to clean the sediment therefrom and facilitate the passage ofthe liquid through its holes; and the constructive features areindependent of the means for operating the spindle which rotates thebrush. As such spindle may, therefore, be operated either by hand or bypower, both constructions are illustrated herein.

The invention provides means of connectin to a supporting base aperforated cylindrical shell lined with a wire cloth, these partsforming a vessel into which the liquid to be strained is received; andsuch straining device is secured removably within a receptacle whichreceives the strained liquid, and from the bottom of which receptacle itcan be drawn at pleasure. The removability of the cylindrical strainerpermits it to be taken from the receptacle when it is necessary toremove the sediment accumulated in the strainer; but the inventionfurther provides means of obviating such removal of the straining devicefrom the receptacle, thus saving considerable time when it is necessaryto clean out the sediment, and avoiding the disconnection andreconnection of the several parts. Such cleaning of the screening devicewhile in the receptacle is effected by mounting the receptacle upon ahinged frame which holds the straining device, when in operation, in avertical osition around the end of the brush-rotating-shaft; but whenthe screen requires cleaning, such hinged frame may be tippeddownwardly, thus holding the cleaning device in a nearl horizontalposition where its open top 1s fully exposed,

and the cleaning can be performed with great facility.

Where the straining device is supplied with paint from a reservoir-tank,the tank is commonly furnished with a stirrer and a verticalstirringshaft extended 'upward therefrom, and such shaft may be readilyconnected by a belt with the brush-spindle. By sustaining suchbrush-spindle in bearings upon the tank, it is su ported in its normaloperative position in ependently of the straining device, and the lattermay, therefore, be swung downward for cleaning without interference fromthe brush.

The details of construction will be understood by reference to theannexed drawing, in which- Figure l is a plan of the strainer connectedwith a reservoir-tank; Fig. la is an elevation of bars J, K and L; Fig.2 is a side elevation of the same, with the nearer bar L broken away,and its sloping bracket-leg removed; Fig. 2 is a side elevation, andFig. 2h a plan of the same straining devices, with means for operatingthe spindle by hand; Fig. 3 is a vertical section of the strainingdevice and the receptacle with an elevation of the brush-spindle and thebrush; Fig. 4 is an elevation of the perforated shell, and Fig. 5 is aplan of the same; Fig. 6 is a diagrammatic plan of the wire cloth; Fig.7 is a plan of one of the hoops for securing the same within the shell,and Fig. 8 is a plan of the base for the shell and wire cloth; Fig. 9 isan elevation of the tie-bolt h.

Fi s. 1 and 2 show a reservoir-tank A for the liquid to be strained,with a stirringshaft B extended from the top, also a brushspindle Cmounted in bearings D upon the tank and having a pulley E u on its topwith belt F connecting it to t e stirringshaft B'. A receptacle G isshown of square form supported below the cock H upon the front of thetank A and containing the cylindrical straining device. The cock H isomitted from Fig. l, but its location indicated by dotted lines H. Suchreceptacle has angles I upon its opposite sides forming ledges tosupport it upon ahinged frame having side-bars J andfront-bar K. Thereceptacle is supported by the ledges I, and in operation tted close tothe bar K and held in such position by movable stops I upon theside-bars J. Brackets L are projected from the legs supporting the tankA and are provided at the front endwith swinging buttons a adapted toengage the heads of screws b inserted in the frame-bar K near itsopposite ends. The buttons are formed with slots c which clear them fromthe screws b as soon as the screws are loosened, such clearance beingindicated by the dotted lines a near the right hand end of the bar K.When the hinged frame is secured in a horizontal position by the buttonsa, the receptacle G holds the straining device centrally beneath thebrush-spindle C with the brush inside the wire-cloth, as shown in Fig.3. lVhen the buttons are released, the hinged frame with the receptacleand straining device can be swung downwardly, as shown in dotted lines Jand G in Fig. 2, which exposes the open top of the straining device forcleaning out the same.

The screening device is constructed with a base-plate d a cylindricalshell e having numerous perforations e', and a lining of wire-cloth fwhich is held within the shell by hoops g. Such hoops, as shown in Fig.7 and at the right hand end of Fig. 3, are formed of a wire with theends coupled to gether by a sleeve It soldered upon one end of the wire.Such hoops are made to fit within the wire-cloth very tightly, and areinserted by first placing them in an inclined position within the clothwith one edge near the top or bottom of the same, and then pushing thehoop into a horizontal posit-ion which locates it either at the top orthe bottom of the screen, as shown in Fig. 3. The wire-cloth or net fis, in practice, made with overlapping ends f indicated only in Fig. 6,the brush being rotated so as to assl smoothly over the lap of thewire-c oth, which is held firmly by the hoops until it is wornsufficiently to need renewal, which the removal of the hooks readilyermits. The cylindrical fixtures are hel detachably upon the base-plateby tie-bolts k inserted through holes j near the edges of the baseplate,and provided with hooks k upon `their upper ends fitted to notches Zupon the upper edges of the shell e. The tie-bolts pass upward close tothe outside of the shell, thus centering it upon the base-plate, andnuts m upon the lower ends of the bolts serve to clamp the partstogether securely and detachably. These parts constitute the screeningdevlee, which is supported within the receptacle above its bottom uponledges n and clamped thereon by plates o secured b bolts p upon twoseats g on the top of t e receptacle. The plates have hooks 0 which tWithin the top edge of the screen and center it in the receptacle. Thescreening device and receptacle thus form a structure which can be setin any required situation to receive the end of a brush-spindle with abrush C to operate upon the screening cloth, and the application of suchstructure to a frame below the brush-spind1e upon the tank furnishes anoperative connection with such brush and tank. The connection of thebrush-spindle with the stirring-shaft B rotates the brush continuouslywithin the straining device and clears the pores of the cloth fromsediment, which accumulates upon the baseplate d, the liquid whichexudes through the cloth escaping by the perforation e in the shell e,and runs down the same into the bottom of the receptacle, which may besloped as shown in Fig. 2, and provided with a gate a' to draw thestrained liquid therefrom.

The mechanism for rotating the brushspindle by hand is shown in Figs. 2aand 2b, the construction of the receptacle and the screening device beinidentical with that shown 1n the other gures, and provided With theangles or side-bars I by which it can be supported upon the same frameas the receptacle shown in Fig. 1, or upon any other suitable firmsupport while straining the liquid. The bearing r for the brush-spindleC2 is attached by a spider s to a skeleton frame t which 1s supporteddetachably upon the upper edge of the receptacle. A shaft c is supportedin bearings u upon the skeleton frame and spider, and is connected withthe brush-spindle by bevel-gears w. A hand-crank a: upon the shaft oserves to turn the brush-spindle by hand, and the openings within theskeleton frame t permit the liquid to flow from a supply cock into thescreening device. The weight of the brush-spindle and its attached partssuiiices to hold the brush in the proper position when in operation; butthe skeleton frame with the brush-spindle and its gearing can be liftedfrom the receptacle whenever it is desired to clean out the screeningdevice. If the receptacle be su ported upon a hinged frame, it can Eetipped downward after the skeleton frame and gearing have been removed,and the screen thus cleaned out without removing it from the receptacle.The suspension of the brush-spindle and brush permits the receptacle tobe placed beneath the same or removed therefrom without having to detachany connecting parts, as the brushspindle has no bearing in the bottomof the screen and is not in any Way connected to the receptacle. Suchfacility for separating the parts permits the frequent cleaning of thereceptacle and brush, which greatly promotes the eilicient operation ofthe apparatus.

Having thus set forth the nature of the invention what is claimed hereinis:
